I’ve had my Zabbix install set up to notify me if the remote server has a high ping using this expression:
{__Remote_Hosts:icmppingsec.avg(30)}>120
The problem is, if your network is congested, it can really hit often. I recommend moving the failed ping average up to 500, and adding another trigger:
{__Remote_Hosts:icmpping.max(120)}<1
This checks for no ping within 120 seconds (or 2 minutes) so it gives you a better idea if the host is "down" or just seeing a high ping latency.
